For me, what happens, in Safari and Firefox, is I click, a popup opens,
an dit's too small. THe iamge loads, and when the image loadend event
occurs, the popup resizes. the popup does not seem to want to make the
map scroll (but I don't think the anchored popups do that) so it's still
somewhat too small, but the image stays the same after it is oaded and
when i click again.

So, for me, this seems to work. Is this not the behavior you're seeing?
